Question

我在Python中有一个小型多线程应用程序，它最近给了我一些错误：

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/local/Cellar/python/2.7.12_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()
  File "enrichment/twitter_enrichment.py", line 368, in run
    self.get_user()
  File "enrichment/twitter_enrichment.py", line 332, in get_user
    self.queueWorkItem.do_work(self.twitterClient)
  File "enrichment/twitter_enrichment.py", line 300, in do_work
    return work(twitterClient)
  File "enrichment/twitter_enrichment.py", line 284, in fetch_timeline
    self.user.newest_tweet_id_str
  File "enrichment/twitter_enrichment.py", line 94, in twitter_drain_timeline
    timeLine = twitter_fetch_timeline(client, user_id, since_id=since_id, max_id=max_id)
TypeError: 'NoneType' object is not callable

方法twitter_fetch_timeline在父线程中设置。

Here是启动我的线程的代码。

此应用程序运行一段时间，然后突然以这种方式失败。

在当前失败的同一方法中，我最初收到错误NoneType object does not have attribute debug，因为我在父线程中创建的记录器实例上调用了logger.debug(...)。我用以下代码解决了这个问题，但现在怀疑我正在修复症状而不是问题：

    try:
        logger
    except NameError:
        logger = None
    finally:
        if logger == None:
            import logging
            logger = logging.getLogger('Twitter Enrichment')

我错过了什么根本问题？
